Abstract (en)
[origin: EP0568511A1] The invention relates to a screen device. A frequency selective screen means (3) and a plate (4) displaceable relative to the screen device (3) are included in the screen device. In a first position of the plate (4) the screen device allows radiation to pass while in a second position radiation within the transmission range of the screen means is suppressed. The screen device is , for example, suitable to be include in a radome for a radar antenna and enables a reduction of the risk of being detected by, for example, an enemy radar. <IMAGE>
